[#507] waitset adjustments

[elfenpiff]

Notes for Reviewer

• DeadlineQueue::missed_deadlines() callback needs to return CallbackProgression so that the user is able to stop handling missed deadlines when required.
• WaitSet::try_wait_and_process was renamed to WaitSet::wait_and_process_once since the function was actually blocking in contrast what the name suggested with the try_ prefix
  • behavior adjusted, blocks until the first event arrives, then handles all events and returns, to make it usable in external event loops.
• WaitSet::wait_and_process and WaitSet::wait_and_process_once callbacks need to return CallbackProgression to terminate event handling whenever required - this replaces the buggy WaitSet::stop() call.
